Struct rustc_mir::const_eval::machine::MemoryExtra[−][src]

pub struct MemoryExtra {
    pub(super) can_access_statics: bool,
}

Fields

can_access_statics: bool
Expand description

We need to make sure consts never point to anything mutable, even recursively. That is relied on for pattern matching on consts with references. To achieve this, two pieces have to work together:

  • Interning makes everything outside of statics immutable.
  • Pointers to allocations inside of statics can never leak outside, to a non-static global. This boolean here controls the second part.
